An application of iodine chemistry to oxidation-reduction titrations for the quantitative analysis in certain chemical compounds, in which iodine is used as a reductant and the iodine freed in the associated reaction is titrated, usually in neutral or slightly acid mediums with a standard solution of a reductant such as sodium thiosulfate or sodium arsenite; examples of chemicals analyzed are copper(III), gold(VI), arsenic(V), antimony(V), chlorine, and bromine.
Industry:Chemistry
Any of the different configurations in which the stationary phase is contained.
Industry:Chemistry
A cell containing the sample in the optoacoustic detection method; equipped with windows through which the laser beam enters the cell and a microphone for detecting sound.
Industry:Chemistry
Device for detection of presence or concentration of liquid solution ions, such as with a pH meter or by conductimetric techniques.
Industry:Chemistry
A method of separating and analyzing mixtures of chemical substances by chromatographic adsorption.
Industry:Chemistry
A chromatographic procedure in which the stationary phase consists of ion-exchange resins which may be acidic or basic.
Industry:Chemistry
Electroanalysis by measuring at a working electrode the rate of change of current versus time during a titration; the potential is controlled.
Industry:Chemistry
A method of chemical analysis based on the absorption or attenuation by matter of electromagnetic radiation of a specified wavelength or frequency. The radiation interacts with specific features of the molecular species being determined, such as the vibrational or rotational motions of the chemical bonds. The radiation can also interact with specific atoms or the whole molecule, for example, by causing the molecule to change its electronic energy state.
Industry:Chemistry
Chromatography in which the adsorbent material is saturated with the same mobile ions (cationic or anionic) as are present in the sample-carrying eluent (solvent), thus repelling the similar sample ions.
Industry:Chemistry
The study of electrode surface properties, such as surface area.
